Fountain Flow™ provides total bioburden results in under 15 minutes within filterable products. Fountain Flow™ is an imaging flow cytometer that combines high speed flow cytometry with the sensitivity of video epifluorescence microscopy in one instrument platform. The method is based on LED-induced fluorescence of labeled particles and requires no filtration step.
Fountain Flow™ is suitable for transparent and translucent fluids, such as water, biopharmaceuticals, pharmaceuticals, blood, and beverages. It can be used for detection of µm-size bacteria to multi-millimeter-sized multicellular organisms in the presence of high photometric background, including unbound fluorescent dye. This facilitates use of the technique in situations where cells are unwashed.
